Rumble, The Mechanized Menace
Flamespitter: Rumble torches the area in front of him with his flamethrower dealing damage to all units in a cone for several seconds. While in the “Danger Zone,” this spell deals additional damage.
Scrap Shield: Rumble creates a shield blocking incoming damage for several seconds and granting a short duration speed boost. While in the “Danger Zone,” the shield’s strength and speed boost increase.
Electro-Harpoon: Rumble launches a missile that deals magic damage and applies a stackable slow on the target. A second shot can be fired for no additional cost within several seconds. While in the “Danger Zone,” the damage and slow percentage is increased.
The Equalizer (Ultimate): Rumble calls down a line of rockets over the target location. Enemies in the scorched area take damage over time and are slowed.
Junkyard Titan (Passive): Rumble's abilities generate heat. When Rumble is above 50 heat, he is in the "Danger Zone," causing all his basic spells to have additional effects. When Rumble reaches 100 heat he overheats, silencing himself and causing his physical attacks to deal additional magic damage. Rumble loses heat over time.
